Finally I did the main enemy to Icelectric -_- Icelectric and Ilectra hates him because he killed kind of "icelectric" dragons in the past , Icelectric and Ilectra was just a babies ! And surely between the kind was their parents T_T . Some informations about him :

Shirdor is a special kind of the shadow dragon . His elements are : SHADOW , DARKNESS , DARK ICE and DARK ELECTRICITY (the last two he gets after killing the "icelectric" kind of dragons) . His symbols on his head and his legs and under and above the eyes are the symbols of the darkness and if they're lighting , he released him biggest powers . His goal is to kill all the dragons on the world because of all their powers he wants to have . He didn't killed Icelectric and Ilectra because he wanted to show them , how strong he will be in the future .
